Hey guys, maybe someone here can lend some insight. In my EF hatch, my speedometer is way off. It reads higher than my car is actually moving. The amount it's off varies depending on speed. If I'm doing city cruising around 30-40 mph it might read 5-10mph faster than my car is actually going. When I get up on to the highway it gets worse and could read as much as 15-20mph off. I have 14in wheels. they aren't the stock ones but the stock ones are the same size i believe. B18a engine and Tranny w/ cable VSS. Does anyone know what could be causing this? I don't know if its related but my car also Revs around 3.5k-4K when doing 65-70mph on the highway. Is that normal for the LS tranny? I thought I was supposed to have the longer gearing that kept the rev's lower. Thanks I appreciate any Input.
